A video "hello!" from Susan, Monday Jan 27

Hi everyone! Here's a little video to say hello ;) 

I hope that everyone is doing well, keeping warm and cozy, despite the harsh winter weather conditions in many places where we live! Take good care, and hope you have power and are not completely snowed in!

In the video above I shared a very cool math toy/ math manipulative you might be interested in: The Yoshimoto Cube (Wikipedia link), discovered in 1971 by Naoki Yoshimoto, a Japanese designer. 

Here's a Wolfram entry with interactive animation showing how the Yoshimoto Cube unfolds -- and a great YouTube video of the Yoshimoto Cube #1 (the gold and silver version). This version is available via the Museum of Modern Art shop in New York (MoMA design store link), but it's quite pricy these days! (I have one that I bought there for a better price about 10 years ago...)

The multicolour one I showed you in the video came from Staples, of all places -- and it was not expensive! (It's worth keeping an eye on the little items near the checkout at your local Staples store, as they often have fascinating math puzzles and toys as novelty gift items...) I also found a couple of them for sale on Ebay.

And if you explore further, there are more Yoshimoto cubes besides #1! Here are instructions on how to make your own Yoshimoto cube #3 -- and you can find others too!
